stood that the novel features of the inven- 1e tion may be embodied inthe enumerated articles and utensils.

s The primary object of my invention is the provision of a" sectional,telescopic drinking cup of this character, which may be extended tofullposition for use and the sections positively'locked and supported toinsure .a rigid structure. And while so extended and locked, leakage ofthe contents of thecontaineris prevented andv possibility 'of accidentalcollapse 'of the container is eliminated. y

In carrying out my invention I provide thesections or ltaperingrings ofthe collapsible cup with co-acting means whereby, after the cup has beenextended, asimple twisting or turning movement of the sections (ex-.cept thebottom section) will cause the adjoining sections to be lockedtogether to form a rigidstructure. And by a reverse twisting or rotarymovement, the sections may successively be unlocked in order that thecup may be collapsed and the sections returned to concentric position. I

With these ends in view the invention consists in certain novel featuresof construction 'and combinations "and arrangements of parts as willhereinafter be more fully pointed out and claimed.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention wherein the parts are combinedand arranged according to the best mode I have thus far devised for thepractical application of the principles of my invention. 1 It will beunderstood that I have shown one 'exemplification ofmy invention, andthat changes and alterations may be made therein, withinthe scope of myclaims,witho'utdeparting from the spirit of my invention.

Figure 1 is a vertical sectional view ofla drinking cup embodying myinvention, shown partly in perspective, with the cup in extendedposition and the cup sections v Figure 2 is a view similar to Figure 1,showing the telescoping sections before they "are turned to interlockedposition.

Figure 3 is a vertical sectional view in perspective showing the cup incollapsed position.

Figure 4 is a face view of a portion of two sections showing the lockingelements.

Figure 5 is a vertical sectional view at line 5'5 of Figure 4L. i In theform of the invention as shown in the drawingsI utilize a comparativelybroad base or circular disk .A composed of suitable material andprovided with a countersunk center or recess B m which the bottomring orsection 1 of the cup is fixed, as by means of the flange A on the bottomA of the section 1.

Four telescopicsections, or tapering rings, are illustrated in thedrawlngs and designated 1, 2, 3, and 4, but it will be understood that agreater or less number ofsections may be utilized if desired. Thesetelescopic sections or taper ng rings increase in diameter 1, andthey'may be stamped from light metal to proper size and shape, or othersuitable material may be, used in the composition of these sections. henthe cup is extended the sections are in frictional contact, but in manyinstances, and due to frequent causes, while the friction is sufficientto prevent leakage, the friction is not adaquate for the support of thesections to holdthe cup cx- Forthis purpose I provide p ositive lockingmeans, comprising co-acting members on adjacent sections, which whenbrought into proper relationship [will lock the sections of-the extendedcup into a rigid structure.

It will be seen that the bottom section 1 is provided with. a pluralityof vertically disposed, exterior protuberances or heads 5, spaced atregular intervals around the section. The second section 2 is providedwith a complementary set of interior sockets 6, which, when alined withthe exterior-heads 5 will permit the section 2 to telescope over W n thecup is extended the section 2 is. no

turned slightly to move the head and socket out of alinement or registerin order that the head may be engaged with the section 2 to retain thelatter in uplifted position.

Sections 3 and 4: are each provided with a series of interior verticallydisposed heads 5 adapted to be locked with the upper enclosed edges ofthe sections 2 and 3 when the cup is extended.

Intermediate sections 2 and .3 are fashioned with exterior recesses orsockets 6 complementary to the sets of heads 5, and these sockets areadapted to receive their heads when the sockets and heads are alin'edand the cup is collapsed. Thus it will be apparent that with thecomplementary series of sockets and heads in alined position, theextended cup may be collapsed by pressure on the top section totelescope the sections, and the bosses 7 of the heads are seated in thesockets. i

In locking the sections of the extended cup, the sections aresuccessively turned, and this relative, successive movement of thesections is limited. Thus the locking ends of the heads are fashionedwith transversely extending, inclined shoulders 8, which when the cup isextended are situated partly out side their sockets, and adapted toengage with the edge, 10, of the sockets as 6 at the rim of a section.As one section is turned with relation to another section this inclinedshoulder acts as a wedge at the point 10 to tighten the sections of thecup and render them leakproof. The end, 11, of the inclined shoulder, 8,is disposed at all times within its socket and thus by contact at thepoint- 10 the shoulder limits the relative movement of the adjoiningsections when they are turned, and the motion of one section issuccessively imparted to a succeeding section, until all are lockedtogether.

Upon reverse rotary movement or turning of the sections to collapse thecup, the point 11 of the shoulder 8 contacts with the wall of a socketat 10, and the rotary motion is thus imparted successively to thesections. When all the sections have been freed from the wedging actionof the inclined edges or shoulders, the sections may be telescoped tocompact concentric position.

It will thus be apparent that by holding the bottom section of thecontainer in one hand, the top section may be grasped by the other handand pulled, and as each succeeding section is frictionally engaged withthe preceding section, the sections are successively drawn out to extendthe container. Then by a twist'of the wrist, the sections aresuccessively locked together by wedge action and the container is readyfor use. The sockets are of such size in relation to the angle of taperof the cup as to be completely covered by the adjacent section or ring,thus insuringagainst possibility of leakage when the cup is extended.

In collapsed or telescoped position, the bosses T of the heads areseated in the sockets, while the greater portions of the heads arelocated between the walls of the concentric sections. IVhile the headsand sockets are referred to as being stamped from the walls of thesections, it will be obvious that these elements may be fashioned inother manner, and it will also be apparent that the dimensions of thesockets and heads, and the numberutilized, may be varied. The size ofthe sets of sections may also be varied, depending upon the nature ofthe re,-

ceptacle or container and its uses, and other changes may be made withinthe scope of my appended claims.

In claims 1, 2, and 3, telescoping section refers to the narrowersection ,Which pasess socket portion on the edge of the adjoiningtelescoping section to permit collapsing whereby when the container isextended and its sections relatively turned, the projecting head on onesection engages against the edge of the adjoining section and thesections are.

locked together.

2. The combination in a collapsible container composed of telescopictapering sections, of an exteriorly projecting head on'a 'iootelescoping section and a complementarysocket portion on the edge of theadjoining telescoped section to permit collapsing whereby when thecontainer is extended and its sections relatively turned, the head onone section engages against the edge of the adjoining section and thesections are locked together. i

3. The combination in a collapsible container composed of telescopictapering sections, of a head on one section and a complementary socketportion on the edge of the adjoining section, the head formed so as toengage the edge of the adjoining section in extended position; and tokeep coupled with its socket in collapsed ajndfpartly collapsedpositions.

4. The combination in a collapsible container composed of telescopictapering sections of a headon one section and a complementarysocketportion on the edge of the adjoining section, the head having ashoulder inclined to the horizontal, adapted to engage the wall ofitssocket as described.
